Pratt &
Whitney (P&W) started in 1925 and is now the worlds largest producer of aircraft
turbine engines (military and civil). The JT8 series originally powered the B727 aircraft
but developments to reduce noise and increase thrust has extended its use for the MD80
series of aircraft. The PW range of engines is used on most of the medium/large aircraft
(Boeing, Airbus, MD). The PW4084 (the 84 represents the static thrust in 1000lbs) is a new
large engine for the B777 type aircraft. The engine is expected to be developed to produce
over 100,00lb thrust. The company is currently working with Asian partners to produce a
new range of engines (PW6000 series) in the 67 - 107kN thrust range which would be
suitable for the proposed 100 seat feeder linear designs.
